The Bluebirds’ stopper has been one of the Premier League’s top glovesmen this season, performing excellently despite his team being embroiled in a relegation dogfight.
His fine displays have led to rumours that Spurs are interested in his signature, as they plan for the possible loss of Hugo Lloris at the end of the current campaign.
The French ace has already confessed that he may be forced to leave north London in search of Champions League football – which looks unlikely to happen with the Lilywhites – for next term, with PSG interested.
Marshall is being touted as a replacement for him on the back of his terrific showings, but the 29-year-old Scot says that he is not thinking about his future right now:
“I am desperate right now to try to help keep this club in the Premier League,” he is quoted by The Express.
“At this moment in time my personal career does not really come into it. I am going to be judged over these last games now.
“That’s me, all the other players and the club as a whole.
“I will be concentrating now on keeping Cardiff up. We’ve got a huge game coming up against Crystal Palace.
“The focus is on that and getting the three points. That is the main aim right now.”
Cardiff are currently three points from safety with six games to play.
